Enter system view. system-view N/A2. Enter Layer 2 Ethernetinterface view or Layer 2aggregate interface view.• Enter Layer 2 Ethernet interfaceview:interface interface-typeinterface-number• Enter Layer 2 aggregate interfaceview:interface bridge-aggregationinterface-numberN/A3. Set the link type of the port.• Configure the port as a trunk port:port link-type trunk• Configure the port as a hybridport:port link-type hybridBy default, the link type of aport is access.4. Assign the port to the originalVLANs and the translatedVLANs.• port trunk permit vlan vlan-id-list• port hybrid vlan vlan-id-list taggedBy default:• A trunk port allows onlypackets from VLAN 1 topass through.• A hybrid port is anuntagged member of theVLAN to which the portbelongs when its link type isaccess.5.
